PROXIMA CENTAURI is a red dwarf star about 4.24 light-years distant inside the G-cloud in the constellation of Centaurus.

It’s mass is about an eighth of the Sun’s and its average density is about 40 times that of the sun.

Although it has a very low average luminosity, Proxima is a flare star that undergoes random dramatic increases in brightness because of magnetic activity.

The star’s magnetic field is created by convection throughout the stellar body, and the resulting flare activity generates a total X-ray emission similiar to that produced by the Sun.
